The way I see it there's pain and then there's damage. My second baby has a high arched palate and a cyst on her upper lip. Her latch is atrocious and she looks ridiculous when she feeds. Every feed was really quite painful for eight months. Especially at night when I was lazy and didn't actively support her latch. It is still uncomfortable at 17 months quite a bit of the time, but I'm committed to breastfeeding and there is no visible damage, so it's not doing me any harm. For me it's bearable and that is a very personal decision. It doesn't psychologically impact on our realtionship and I think we both get more out of breastfeeding than I lose in being uncomfortable. I think they key part is that I know what the porblem is and that it isn't fixable, whilst I suspect that your problem will fix itself in time.
